Question

3. Water freezes at 0 Celsius and 32 Fahrenheit. What is the y-intercept and what does it mean?

Answer 1

I did most of it already. Just can't figure out what the y is http://imageshack.com/a/img824/1580/skdw.png

Answer 2

The y-intercept is -160/9

The y-intercept separates celsius and fahrenheit.
We know x = celsius and y = fahrenheit
On the graph, you can look at the line, graphically, when x = 0, and y = 0. We know that water boils at 100 celsius and 212 Fahrenheit. You can plug in options into the y intercept to get various representations.
